Joan read 9 chapters in 4 hours. If she continued to read at the same rate, how many chapters
would she have read in 2 days?
a) 4.5 chapters
b) 108 chapters
c) 21.3 chapters
d) 0.9 chapters

b) 108 chapters

Step-by-step explanation:

there's 24 hours in a day and it takes joan 4 hours to read 9 chapters, so first you need to divide to find out how many sets of 4 hours are in 24.

÷

multiply 6 by 9 to find how many chapters she read in a day.

×

multiply the product by 2 to get the amount of chapters she would have read in two days.

×

32/80  

91/140

the last one 54 doesn't go into 45. 54/100 ?
